“Setting Up a Domain and a Post Office in a Heartbeat Cluster,” on page 307 .
30.5 Planning a New Library for a Clustered Post
Office
The considerations involved in planning a new library in a clustering environment are essentially the
same as for any other environment. However, in a Linux cluster, you should not plan to locate a
document storage area on a remote server. If you choose to place it outside the post office directory
structure, it should still be located on the same server with the post office directory. Ideally, you
should create a dedicated post office just to house the library. This provides easy access for all users.
You can plan a library for a clustered post office by following the standard instructions provided in
“
Creating and Managing Libraries ” in the GroupWise 7 Administration Guide and filling out the
“ Basic Library Worksheet ” or the “ Full-Service Library Worksheet ”. Then provide the library
information on the GroupWise Clustering Worksheet.

30.6 Considering How to Install and Configure
the Linux Agents in a Cluster
There are several cluster-specific issues to consider as you plan to install the Linux MTA and POA
in your clustered GroupWise system:

Section 30.6.1, “Recording Secondary IP Addresses for the Agents,” on page 290
Š Section 30.6.2, “Determining Appropriate Heartbeat Constraints for GroupWise Cluster
Resource Groups,” on page 291

Section 30.6.3, “Planning the Linux Agent Installation,” on page 293
30.6.1 Recording Secondary IP Addresses for the Agents
By default, the GroupWise agents listen on all IP addresses that are bound to the server. This means
that any time there is a possibility of two of the same type of agent starting on the same node, it is
important that each agent use the secondary IP address associated with its cluster resource group, not
HEARTBEAT CLUSTERING WORKSHEET
Under Item 8: Cluster Resource for Post Office , specify the name of the cluster resource group that will
represent the post office (for example,
group_po2
), the name of the resource for the POA (for example,
resource_poa2 ), and the name of the post office, including its domain (for example, Waltham1.Sales).

Under Item 6: Document Storage Area Location , mark where you want to create the library’s document
storage area.
